RELATED APPLICATION SECTION

This application is related to co-pending U.S. patent application No.TBD, filed on TBD entitled, “RESPONDER-READY REPORTING NETWORK” by LeaAnn McNabb and Prakash Iyer, having Attorney Docket No. TRMB-4081, andassigned to the assignee of the present application.

BACKGROUND

Most buildings have a set of blueprints on file with a public agencysuch as a building inspector. For many buildings, these blueprintsreflect the proposed or intended layout of the building. However, duringthe construction process, changes often are made to the layout of thebuilding which may not be reflected in the blueprints on file.Furthermore, these blueprints may be stored as multiple records atmultiple locations making it difficult to locate and access theserecords by emergency responders during an emergency, especially onweekends and holidays when no-one is typically working at the publicagency's office. As a result, emergency responders may not have anaccurate, if any, set of documents which reflect the currentconfiguration of a building, or other selected environment during anemergency.

Most public buildings display an evacuation map showing the presentlocation of a person viewing the map and the route to the closest exit.However during an emergency, a person may have a hard time rememberingthe route to the closest exit due to panic or excitement. Furthermore,the map is static in that it only shows one route which may becomeblocked or unusable due to heat, fire, smoke, debris, etc. In such aninstance, the person may not have enough information to safely evacuate.

FIG. 1 is a diagram of a responder-ready reporting network and emergencyevacuation navigation system 100 in accordance with various embodiments.In accordance with various embodiments, system 100 comprises a set ofdigital building plans 101 which are accessed by a control system 150and stored in a non-volatile database 160. System 100 further comprisesreal-time environmental monitors 102 and a positioning networkcomprising position monitors 103 disposed within a selected environment,and manual inputs 105 coupled with control system 150. In the embodimentshown in FIG. 1, control system 150 is configured for two-waycommunications with cellphones 120, in-room devices 121, fixed displays123 (e.g., a wall-mounted electronic display device, an informationkiosk, etc.), wearable devices 124 (e.g., an optical head-mounteddisplay such as Google Glass, a wrist-worn computer system, etc.),tablets/phablets 125, and an emergency responder agent 180. The term“phablets” refers to a class of handheld devices which have a largerform factor than a cellphone, but smaller than a typical tabletcomputer. In accordance with various embodiments, communication betweencontrol system 150 and the other components described above can beaccomplished using wired or wireless communication links, or acombination thereof.

In accordance with various embodiments, system 100 is used to record, ina single data package, the most current configuration of a selectedenvironment for use by emergency responders. For the purposes of thefollowing discussion, the selected environment monitored and reported bysystem 100 will be described as a building (e.g., building 400 of FIG.4). However, in accordance with various embodiments, the selectedenvironment comprises a constructed environment such as a building,refinery, mining operation, a subway or other sub-surface feature, aship, etc. in contrast to an open space out-of-doors environment. Thatis, the selected environment is an environment, such as an indoorenvironment or constructed environment, in which GNSS signals broadcastfrom GNSS satellites cannot be received reliably or even at all.Additionally, system 100 can be used to monitor, in real-time,environmental conditions of building 400, to automatically detectemergency events, and to provide real-time reporting of conditions inbuilding 400 (e.g., real-time reports of environmental data) toemergency responders during an emergency. In at least one embodiment,system 100 is configured to dynamically generate alternate evacuationroutes in real-time based upon reported environmental conditions withinbuilding 400 as well as to report changes in evacuation routes toemergency responders. As will be discussed in greater detail below,system 100 is also configured to monitor the position of devices (e.g.,within building 400) at least during an emergency and to report theposition of these devices to an emergency responder agent 180. As willbe discussed in greater detail below, emergency responder agent 180 canbe a person working for an emergency responder agency, or computersystem (e.g., a desktop computer system, a laptop computer system, atablet computer system, a smartphone, a wearable device (e.g., anoptical head-mounted display such as Google Glass, a wrist-worn computersystem, etc.), or other type of user portable computing device) used byan emergency responder agency, or an agency itself such as an emergencycall center (e.g., 911 call center, E911 call center, a NG911 callcenter, etc.). System 100 can also be used to facilitate communicationsbetween emergency responders and people/devices within building 400.Furthermore, system 100 is configured to report to emergency responderswhen people/devices have successfully reached an evacuation location.According to various embodiments, an evacuation location can be outsideof building 400 comprising system 100, or within building 400 such as atornado shelter, fireproof room, earthquake shelter, etc.

In accordance with various embodiments, digital building plans 101comprises a set of as-built blueprints of building 400 monitored andreported by system 100. The as-built blueprints represent theconfiguration of building 400 as it was implemented rather than how itwas envisioned in the building application process. In accordance withvarious embodiments, building plans 101 at least include 2-D plans ofbuilding 400 and can further include 3-D plans as well. For example,often during the construction process changes have to be made to theconfiguration of building 400 due to unforeseen circumstances, ormodifications requested by a client or regulating authority. This caninclude the location of walls, entrances, stairwells, elevators,escalators, and windows, as well as utility features such as pipes,electrical wiring and circuit boxes, gas lines, construction materialsused, flammable/toxic materials storage, stand pipes, sprinkler systems,etc. Additionally, the digital building plans 101 can comprise a morecomplete representation than is generally available to the public. Forexample, a hotel guest will have an evacuation map in their room whichtypically shows an evacuation route down a hallway to the nearest fireexit. This evacuation map typically does not show non-public spaces suchas service elevators, corridors, kitchen or storage spaces, etc. whichmay be used as alternate evacuation routes in some instances. Inaccordance with various embodiments, the digital building plans 101 canbe generated in real-time during the construction of building 400, orcan be a set digital blueprints which are subsequently updated.

In the case of older building which may not have a digital record onfile (e.g., having only paper blueprints), a set of digital buildingplans 101 can be created by a third party. For example a service can beprovided by a third party to generate a set of digital building plans101 of a building (e.g., building 400 of FIG. 4). This can be as simpleas using a Global Navigation Satellite System (GNSS) receiver to locatethe features of a building such as hallways, doors, etc., or can be amore comprehensive data set generated using, for example, a 3-D laserscanner to generate a point cloud showing in greater detail the featuresof the building. Alternatively, a surveying total station can be used tocreate a detailed set of digital building plans 101. Other methods ofgenerating digital building plans 101 in accordance with variousembodiments can implement using a position aware image capture device toderive digital building plans using the position of the image capturedevice as well, as its azimuth in some cases, to derive theconfiguration of building 400. It is noted that further processing ofcaptured images, such as photogrammetry, can be implemented to derivethe digital building plans 101. One example of a service capable ofgenerating digital building plans 101 is the Trimble Indoor MobileMapping Solution (TIMMS) by Trimble Navigation Ltd. of Sunnyvale, Calif.This service uses LiDAR and spherical video imaging to generate 2-D and3-D maps of areas, including GNSS-denied areas, wide-area indoormapping, and indoor geo-referenced spherical camera data. Other sourcesof digital building plans 101 can be derived from other imaging sourcessuch as the indoor Google maps service or the HERE maps service providedby Nokia. In another example, the geographical positions of positionaware devices such as cellphones can be received by a mapping system andanalyzed to determine the location of high traffic areas, rooms orspaces which are or are not likely to be occupied, materials used inspaces, location of obstructions, etc. As stated above, control system150 receives digital building plans 101 and stores them as a real-timedigital map 170 in database 160. Control system 150 can also receiveother data to include with real-time digital map 170 which would benefitemergency responders. For example, the location of stand-pipes,sprinklers, building materials, breathing apparatus, fire hydrants inthe vicinity of building 400, location and type of hazardous materialson site, location of gas lines, electrical equipment, access points forelevators, phones and shutoffs, street plans and access points, andspecial conditions or features (e.g., a helipad) can all be included inreal-time digital map 170. Additionally, images of building 400 can beincluded in the data set comprising real-time digital map 170. Forexample, images from each direction, as well as aerial images, can bebeneficial in an emergency. Furthermore, a variety of identifiers suchas building name, building street address, the latitude and longitude ofthe building or features of the building as described above, and otherimages such as interior images, can be included in the data setcomprising real-time digital map 170. This information can be manuallyinput (e.g., manual inputs 105) or digitally accessed by control system150. Because control system 150 is configured to modify real-timedigital map 170 whenever changes are made, real-time digital map 170comprises the most up-to-date and accurate representation of building400 monitored and reported by system 100. This is a great benefit toemergency responders who are often entering the building 400 for thefirst time and are not familiar with the area and/or layout of building400. In particular, aerial images and latitude/longitude information arebeneficial to helicopter pilots in locating building 400. In accordancewith various embodiments, real-time digital map 170 further comprises adisplay of the position, within or proximate to building 400, of eachregistered device (e.g., cellphones 120, in-room devices 121, fixeddisplays 123, wearable devices 124, and tablets/phablets 125). This is agreat benefit to emergency responders in locating people within building400 who may require assistance in evacuating building 400 during anemergency.

In accordance with various embodiments, real-time environmental monitors102 are embedded within the constructed environment monitored andreported by system 100. Examples of monitoring devices comprisingreal-time environmental monitors 102 include, but are not limited to:smoke monitors, heat monitors, gas monitors (e.g., CO monitors, CO₂,monitors, natural gas monitors, radon monitors, toxic fume monitors,etc.), light monitors, radiation monitors, earthquake monitors, cameras(e.g., video cameras, infra-red cameras, thermal imagers, lightintensifying cameras, etc.) and other devices which can reportconditions within building 400 monitored and reported by system 100.Real-time environmental monitors 102 report these conditions, eithercontinuously or periodically, to control system 150 which can use thisdata to update real-time digital map 170 and to dynamically update 190evacuation routes which can be sent to cellphones 120, in-room devices121, fixed displays 123, wearable devices 124, and/or tablets/phablets125. In at least one embodiment, real-time environmental monitors 102will continuously report environmental conditions when an emergency istriggered by control system 150. In accordance with various embodiments,when an emergency notification has been triggered, each of the sensorscomprising environmental monitors 102 will regularly generate anintermittent signal. This provides information to control system 150that the sensors are working. Thus, if control system 150 determinesthat a given environmental monitor 102 has stopped sending thisintermittent signal, it may be assumed that the environmental monitor102 has become damaged such as by a fire. This may affect thecalculation of an evacuation route such as by causing control system 150to re-direct evacuation routes around the damaged environmental monitor102. In at least one embodiment, control system 150 may collect andanalyze additional information from proximate environmental monitors 102as well. For example, if a smoke monitor stops sending the intermittentsignal, control system 150 may access cameras, CO₂ monitors, heatmonitors, etc. proximate to the smoke monitor to determine whether thereis actually a fire in the area proximate to the smoke monitor. If thereis no indication of damage in the area proximate to the smoke monitorwhich has ceased sending intermittent signals, control system 150 maydetermine that it is simply an anomaly and not re-route evacuationroutes to different areas. Thus, in accordance with various embodiments,real-time management of real-time digital map 170 includes, but is notlimited to, updating real-time digital map 170 based upon data sent inreal-time from environmental monitors 102.

In accordance with various embodiments, position monitors 103 areembedded within a constructed environment monitored and reported bysystem 100 and are configured to report the location of a registeredhandheld wireless device to control system 150. In accordance withvarious embodiments, handheld wireless devices include, but are notlimited to, cellphones 120 (e.g., smartphones), in-room devices 121,laptop computer systems, tablet computer systems (e.g., tablets/phablets125), personal digital assistants, personal navigation devices, etc. Itis noted that various embodiments are not limited to handheld devicesalone. For example, at least one embodiment position monitors 103 areconfigured to report the location of other user portable devicesincluding, but not limited to a wearable devices 124 (e.g., an opticalhead-mounted display such as Google Glass, a wrist-worn computer system,etc.). Examples of position monitors 103 in accordance with variousembodiments include, but are not limited to, devices configured tooperate on/in compliance with any suitable wireless communicationprotocol including, but not limited to: Wi-Fi, WiMAX, implementations ofthe Institute of Electrical and Electronics Engineers (IEEE) 802.11standard, implementations of the IEEE 802.15.4 standard for personalarea networks, and a short range wireless connection operating in theInstrument Scientific and Medical (ISM) band of the radio frequencyspectrum in the 2400-2484 MHz range (e.g., implementations of theBluetooth® standard) including Bluetooth Low Energy (BLE)implementations, implementations of the IEEE 1902.1 (RuBee) standard,implementations of IEEE 802.15 (ZigBee) standard, etc. It is noted thatposition monitors 103 are not limited to wireless networks alone and cancomprise wired or wireless communication networks, or a combination ofboth. In accordance with various embodiments, control system 150 isconfigured to monitor and/or report in real-time the location of anyregistered device while it is in building 400 monitored by system 100.Thus, in accordance with various embodiments, real-time management ofreal-time digital map 170 includes, but is not limited to, updatingreal-time digital map 170 based upon data sent in real-time fromposition monitors 103.

In accordance with various embodiments, manual inputs 105 allows anoperator to input data which may not be accessible in digital form bycontrol system 150. For example, registration of handheld wirelessdevices (e.g., cellphones 120, in-room devices 121, wearable devices124, and/or tablets/phablets 125) can be performed via manual inputs105. For example, each in-room device 121 in building 400 can bemanually registered to control system 150, including the room in whichit is normally disposed, using manual inputs 105. Similarly, a guest orvisitor to building 400 can provide the phone number to their cellphone120, wearable device 124, and/or tablet/phablet 125 which can bemanually registered with control system 150 using manual inputs 105.Alternatively, devices such as cellphones 120, in-room devices 121wearable devices 124, and/or tablets/phablets 125 can be automaticallyregistered using, for example, bar-code readers, radio-frequencyidentification (RFID) devices, wireless Internet, Bluetooth, etc. In atleast one embodiment, a fixed display 123 (e.g., an information kiosk,or other fixed information display) can be located in the lobby ofbuilding 400 so that a user can register their personal handheldwireless devices with control system 150. In accordance with variousembodiments, fixed display 123 can normally be used as aninformation/entertainment device which displays commercials,entertainment, or other content, but can be configured to operate as afixed evacuation device when an emergency notification has beentriggered by implementing evacuation agent program 130 onto fixeddisplay 123. Alternatively, the content displayed on fixed display maybe fed from a remote server. In this instance, evacuation agent program130 will cause the remotely located fixed display 123 to displayevacuation information when an emergency notification has beentriggered. In accordance with various embodiments, user portable devicesas described above as well as fixed displays 123 can also download anevacuation agent program 130 which is described in greater detail below.It is noted that in accordance with various embodiments, fixed displays123 refers to devices which are not intended to be moved from theposition at which they are located. For example, an otherwise portabledevice, such as a tablet computer, can be attached to a wall andimplemented as a fixed, dynamically updated evacuation map usingevacuation agent program 130 in accordance with various embodiments.Alternatively, an information kiosk which is not attached to a surfaceof building 400, but is otherwise too large to be considered a userportable device, can also download an evacuation agent program 130 inaccordance with various embodiments.

In accordance with various embodiments, database 160 comprises anon-volatile data storage repository for storing real-time digital map170 and other information described above which may be helpful toemergency responders. It noted that real-time digital map 170 cancomprise many layers. For example, in one embodiment, real-time digitalmap 170 comprises a 2-dimensional (2-D) map of the building, or everyfloor of a building, being monitored and reported by system 100. Anotherlayer comprising real-time digital map 170 may be a 3-dimensional (3-D)map of building 400. Other layers may comprise photographs, or otherimages, which are tied to particular locations within the selectedenvironment. For example, an icon in the lobby of a 2-D map of real-timedigital map 170 may be a link to one or more photographs of thatlocation which provide emergency responders a better idea of theenvironment they are entering. For some buildings, an indication of howmany people are expected to be on the premises at a given time of theday may be another layer of real-time digital map 170. This may be basedupon historical information, or based upon the number of people who havebeen identified as having entered or exited the premises. In oneembodiment, database 160 is located separate from the building which itis monitoring. Examples of database separate from the building which itis monitoring include, but are not limited to, a remotely locatedserver, a cloud computing environment, and a distributed or networked,computing system. In various embodiments, a remotely located database160 may be privately operated by the entity owning the buildingmonitored and reported by system 100, may be operated by a third partyprovider, or may be operated by the local emergency services. Inaccordance with various embodiments, when an emergency is triggered,control system 150 can forward real-time digital map 170 to an emergencyresponder agent 180. In this instance, emergency responder agent 180comprises a computing device as described above. In one embodiment, thiscomprises sending a web-link permitting the emergency responder agent180 to access database 160 via control system 150. In at least oneembodiment, control system 150 conveys an authorization (e.g., a username and/or password) permitting emergency responder agent 180 to bypasscontrol system 150 and access database 160 directly.

Emergency responder agent 180 can then download real-time digital map170 and emergency responders can access it. In accordance with variousembodiments, real-time digital map 170 comprises various layers ofinformation including, but not limited to, a real-time 2-D and/or 3-Drepresentation of a constructed environment such as building 400,images, etc. Additionally, as data is received by control system 150 viareal-time environmental monitors 102 and/or position monitors 103, thisinformation can be used to update in real-time the information availableto emergency responder agent 180. In one embodiment, control system 150will generate an updated real-time digital map 170 and convey thisupdated map to emergency responder agent 180. In another embodiment,control system 150 will update the real-time digital map 170 stored ondatabase 160 which is then accessed by emergency responder agent 180.Alternatively, control system 150 can generate real-time updates 190regarding building 400 based upon the information received fromenvironmental monitors 102 and/or position monitors 103 and providethese real-time updates 190 to emergency responder agent 180 where theyare used to update a locally accessed copy of real-time digital map 170.In other words, real-time updates 190 comprise real-time reports ofvarious data including, but not limited to, environmental data withinbuilding 400, position information of people within building 400 basedupon data received from cellphones 120, in-room devices 121, wearabledevices 124, and/or tablets/phablets 125 detected by position monitors103 based upon the location of cellphones 120, in-room devices 121,fixed displays 123, wearable devices 124, and/or tablets/phablets 125,and/or manually or verbally reported data received via manual inputs105. In accordance with various embodiments, control system 150 can usea wireless communication interface to communicate wirelessly withemergency responder agent 180. Example wireless communication protocolsdescribed above with reference to position monitors 103 can be used forcommunication between control system 150 and emergency responder agent180 in accordance with various embodiments. In accordance with variousembodiments, this communication between control system 150 and emergencyresponder agent 180 facilitates generating real-time updates 190 ofconditions in building 400 (e.g., from real-time environmental monitors102 and position monitors 103) which permit identifying where and whattype of emergency is occurring on the premises, and the location ofpeople within building 400 who need to be evacuated based upon thelocation of cellphones 120, in-room devices 121, wearable devices 124,and/or tablets/phablets 125 detected by position monitors 103 based uponthe location of cellphones 120, in-room devices 121, wearable devices124, and/or tablets/phablets 125 detected by position monitors 103. Thismay include video feeds from video cameras disposed within building 400.Additionally, the emergency responders may access the wirelesscommunication interface (e.g., 240 of FIG. 2) which facilitatescommunications between the emergency responders and cellphones 120,in-room devices 121, fixed displays 123, wearable devices 124, and/ortablets/phablets 125 within building 400. This gives emergencyresponders the ability to speak directly with people in building 400 toreceive information from these people and to give evacuationinstructions. In accordance with at least one embodiment, control system150 can download a program (e.g., 131 of FIG. 1) onto emergencyresponder agent 180 which facilitates interfacing with control system150 and/or database 160. Additionally, an evacuation agent program 130resident on in-room devices 121 and/or fixed displays 123 facilitatesinteracting with control system 150 to permit downloading and/orupdating a copy of real-time digital map 170 on in-room devices 121 andfixed displays 123, receiving updates on the position of in-room device121, and updates of environmental conditions in building 400 reportedand monitored by system 100. Control system 150 can also downloadevacuation agent program 130 onto a private device (e.g., a cellulartelephone, wearable device 124, tablet/phablet 125, laptop computer,PDA, etc.) which permits interacting with control system 150 using adevice which was not manufactured or originally intended to be used asan evacuation navigation device as will be discussed in greater detailbelow.

Alternatively, database 160 may be located within building 400 beingmonitored and reported by system 100. For example, database 160 may beimplemented as a computer system located in a computer/server room ofbuilding 400. In another embodiment, database 160 comprises a removabledata storage device, such as a removable hard drive or USB flash drive,which is located in a dedicated structure for access by emergencyresponders. As an example, a secured box outside of, but proximate to,building 400 being monitored and reported by system 100 may comprise adata and power connection for a removable hard drive comprising database160. In normal circumstances, this box is secured from public access andpermits updating of real-time digital map 170 while in the secured box.In the instance of an emergency, control system 150 is configured toprovide physical access to the secured box to emergency responder agent180. First, control system 150 can convey to an emergency responderagent 180, the location of the secured box in which database 160resides. In this instance, emergency responder agent 180 is, forexample, a firefighter who is responding to an emergency triggered bysystem 100. In one embodiment, control system 150 can remotely unlockthe secured box in which database 160 is residing so that thefirefighter can disconnect the removable hard disk comprising database160 so that it can be accessed by an electronic device operated by thefire department. Alternatively, if the secured box is not equipped withan electronic lock, control system 150 can send a combination forunlocking the secured box, or the location at which a key for unlockingthe secured box can be found. Alternatively, an emergency responseagency such as the fire department may already have in their possessiona key for unlocking the secured box. Thus, by securing the removablehard drive comprising database 160, the fire department now has accessto an up-to-date representation of the configuration (e.g., real-timedigital map 170) of building 400 and any other information stored ondatabase 160 which is considered useful in responding to emergencies.Furthermore, the removable hard drive may provide information, such aweb link, giving the firefighters Internet access to control system 150.This facilitates receiving real-time updates 190 of conditions inbuilding 400 (e.g., from real-time environmental monitors 102 andposition monitors 103) which permit identifying where and what type ofemergency is occurring on the premises, and the location of peoplewithin building 400 who need to be evacuated based upon the location ofcellphones 120 and in-room devices 121 detected by position monitors103. This may include video feeds from video cameras disposed withinbuilding 400. Additionally, the emergency responders may access thewireless communication interface (e.g., 240 of FIG. 2) which facilitatescommunications between the emergency responders and cellphones 120 andin-room devices 121 within building 400. This gives emergency respondersthe ability to speak directly with people in building 400 to receiveinformation from these people and to give evacuation instructions.

FIG. 2 is a diagram of components of a control system 150 in accordancewith various embodiments. In FIG. 2, control system 150 comprises anemergency responder reporting component 210. In accordance with variousembodiments, emergency responder reporting component 210 is configuredto provide an emergency responder agent access to real-time digital map170. As described above, in accordance with various embodiments thiscomprises conveying a link to a webpage comprising real-time digital map170. This may further comprise discreet messages which separately conveythe link to the webpage as well as login information. In anotherembodiment, emergency responder reporting component 210 can downloadreal-time digital map 170, and other information, directly to emergencyresponder agent 180. This can include downloading a program 131 ontoemergency responder agent 180 which facilitates interfacing with controlsystem 150 and/or database 160. In another embodiment, emergencyresponder reporting component 210 conveys the location of a secured boxat which an emergency responder agent can access the removable harddrive, or other documents, regarding building 400 reported and monitoredby system 100.

In FIG. 2, control system 150 also comprises a map updater 220. Mapupdater 220 is configured to receive information concerning changes tothe physical topography of building 400 being reported and monitored bysystem 100. This can include the addition or removal of walls,modifications of walls (e.g., shortening or lengthening a wall),modifications to materials (e.g., replacing a fabric covering withpaint), location of fixed, semi-fixed, or movable features such asfurniture and/or equipment, addition or removal of flammable materials,as well as what type, location of fire-fighting apparatus, addition ofsprinkler systems, etc.

In FIG. 2, control system 150 also comprises a device position reporter230. As discussed above, in accordance with various embodiments,position monitors 103 are dispersed throughout building 400 beingreported and monitored by system 100. These can autonomously detect theposition of a handheld device or other user portable device such ascellphones 120, in-room devices 121, wearable devices 124, and/ortablets/phablets 125 and report the position of each of these devices todevice position reporter 230. Alternatively, the handheld devices/userportable devices could autonomously determine their position using GNSSsignals, cell tower triangulation, or detection of position monitors 103which yield position information used to derive the position of thehandheld/user portable device. In accordance with various embodiments,the determination of the position of the handheld/user portable devicecan be performed using device position determiner 231, or can bedetermined autonomously by the handheld/user portable device (e.g.,cellphones 120, in-room devices 121, wearable devices 124, and/ortablets/phablets 125). In accordance with various embodiments,handheld/user portable devices such as cellphones 120, in-room devices121, wearable devices 124, and/or tablets/phablets 125 operatingevacuation agent program 130 will automatically report into controlsystem 150 when the device has reached a designated evacuation position.Alternatively, a position monitor 103 located at an evacuation positioncan report this information to device position reporter 230 without thenecessity of an operation performed by the handheld/user portabledevice. This facilitates creating a roll of people safely evacuated frombuilding 400 for emergency responders. This can be checked against aroll of people thought to be in building 400 to help emergencyresponders determine whether people still need to be rescued orevacuated from building 400.

In FIG. 2, wireless communication interface 240 is configured tofacilitate two-way communications between handheld/user portable devices(e.g., cellphones 120, in-room devices 121, wearable devices 124, and/ortablets/phablets 125) and other entities. This can include emergencyresponder agent(s) 180, employees at building 400 who may be able toprovide needed information, or others such as emergency dispatchers.This provides the ability to exchange information which is needed tosafely evacuate building 400 during an emergency, or for reportinginformation such as conditions at a location, or location reporting of auser of one of the handheld/user portable devices. In accordance withvarious embodiments, wireless communication interface 240 can provide,as an example, Voice over Internet Protocol (VoIP) functionalityincluding, but not limited to, Short Message Service (SMS), voice, voicemessaging, etc. over the Internet rather than the Public SwitchedTelephone Network.

In FIG. 2, environmental condition monitor 250 is configured to monitorinformation sent from real-time environmental monitors 102. Inaccordance with various embodiments, this provides the ability to detectdangerous conditions such as fires, toxic fumes, radiation, gas leaks,etc. and report them to control system 150. In response, emergencytrigger 270 can automatically trigger an emergency notification toemergency responder services. Alternatively, emergency trigger 270 canbe manually triggered as well. After an emergency has been triggered,environmental condition monitor 250 can continue receiving informationfrom real-time environmental monitors 102 to facilitate generatingevacuation routes for users of handheld devices such as cellphones 120,in-room devices 121, wearable devices 124, and/or tablets/phablets 125.For example, if a fire blocks a pre-determined evacuation route from abuilding, control system 150 will receive this information viaenvironmental condition monitor 250 and dynamically generate a newevacuation route (e.g., as an update 190 of FIG. 1) for a given locationusing evacuation route generator 260. It is noted that the evacuationroutes for devices such as cellphones 120, in-room devices 121, wearabledevices 124, and/or tablets/phablets 125 may also be sent to emergencyresponder agent 180 so that emergency responders know which routeswithin building 400 are likely to be used during an evacuation.Additionally, as evacuation routes may be dynamically updated orchanged, these changes to evacuation routes will be reported toemergency responder agents 180 in the form of updates 190. In accordancewith various embodiments, emergency trigger 270 can report emergencynotifications to emergency responder agent 180 in a variety of ways. Inone embodiment, emergency trigger 270 can simply send an alarm (e.g., afire alarm) automatically to the appropriate agency (e.g., a 911 callcenter, the fire department, etc.) when an emergency condition isidentified. In another embodiment, emergency trigger 270 can implementthe text-to-911 standard which is being implemented in various regions.Alternatively, emergency trigger 270 can generate a code indicating tothe 911 call center that the emergency notification is a machinegenerated notification of an emergency event. It is noted that themachine generated notification can be routed to other emergencyresponder agents and agencies in addition to, or instead of, the 911call center. In accordance with various embodiments, in response tomachine generated notification, the 911 call center, or other emergencyresponder agents/agencies, will initiate a verification request to aperson designated as a local agent for emergency response activities. Asan example, the cellphone number of the designated local agent can beretained by the 911 call center, or other emergency responderagents/agencies, and in response to a machine generated emergencynotification, the cellphone of the designated local agent can be calledto verify that there is in fact an emergency at the selected location.In accordance with various embodiments, the local agent can provide acode which is registered with the 911 call center, or other emergencyresponder agents/agencies, which verifies the identity of the localagent and/or authority to verify an emergency notification.

In accordance with various embodiments, emergency trigger 270 furthercomprises a next generation 911 (NG911) component 275. NG911 component275 is configured to comply with the standards and protocols of there-designed emergency calling system which is the emerging worldwidestandard. In the past, ad hoc solutions were used to integrate newtechnologies into the 911 system. In other words, as cellulartechnology, VoIP, and other communication methods have been more widelyused, new solutions had to be added onto the existing 911 system topermit locating the caller to the 911 call center. It has beenrecognized that this system is in need of an overhaul in order to meetthe needs of the communication networks now being used. The NG911 systemhas been to be compatible with digital communications both in the UnitedStates and abroad and is based upon the standard Session InitiationProtocol (SIP) which is common to VoIP services and 4G mobile networksand can be used for controlling multimedia communication sessions. SIPdefines the data messages that are sent to begin and end calls, as wellas other data used to initiate calling features such as Caller ID andcall forwarding. Using the NG911 system, a caller device (e.g., acellphone, or computer using VoIP) first obtains its position from anaccess network such as an Internet provider or cellular provider. Theposition information is then sent over an origination network usingemergency call packets to identify that the call is an emergency call.Using the position information for the calling device, the emergencycall is then routed to the appropriate emergency communication center.Among the features supported by the NG911 system is the ability tostream data such as real-time video and voice. In accordance withvarious embodiments, control system 150 is configured to provide theposition information in the emergency call (e.g., the address ofbuilding 400) and can add finer granularity in locating each device(e.g., what floor, hallway, room, etc.) at which each registered deviceis located within, or proximate to, building 400.

Evacuation route generator 260 is configured to generate an evacuationroute for any given location within building 400 based uponpre-determined evacuation planning in conjunction with real-timeconditions within building 400. For example, public buildings areequipped with pre-determined maps of evacuation routes which typicallyshow a user's current location and a route to be followed to anemergency exit. However, these maps do not account for real-timeconditions which may not be foreseen when the maps are created. As anexample, if fire blocks one of the pre-determined emergency routes shownon the map, user's will neither receive timely information of thisobstruction, nor will they receive an updated emergency route to safelydirect the user to an emergency exit. In accordance with variousembodiments, evacuation route generator 260 receives information onreal-time environmental conditions from environmental condition monitor250, and user position information from device position reporter 230 inorder to dynamically generate new evacuation routes when necessary dueto changing conditions. This includes not only handheld/user portabledevices, but fixed display devices 123 such as kiosks and/orwall-mounted displays which can display dynamically generated newevacuation routes.

In FIG. 2, real-time update generator 280 is configured to update, inreal-time, conditions within building 400. As an example, real-timeupdate generator 280 can generate updates to real-time digital map 170which show the location of each handheld/user portable device (e.g.,cellphones 120, in-room devices 121, wearable devices 124, and/ortablets/phablets 125) and thus the location of their respective users.Real-time update generator 280 can further generate updates to digitalmap 170, or to another file in database 160, which provides details ofthe type and location of the event which triggered an emergencyresponse. As an example, real-time update generator 280 can report afire at location 401 of building 400. Alternatively, rather than updatereal-time digital map 170, real-time update generator 280 can simplygenerate updates 190 which go directly to emergency responder agents 180and/or handheld/user portable devices such as cellphones 120, in-roomdevices 121, wearable devices 124, and/or tablets/phablets 125. Theupdate(s) 190 are then applied to the real-time digital map 170 residentupon the device being used.

FIG. 4 shows an example building 400 equipped with a reporting andmonitoring system in accordance with various embodiments. In FIG. 4,building 400 comprises rooms 401, 402, 403, and 404 which are linked bya perimeter hallway 405. Also shown in FIG. 4 are a plurality ofreal-time environmental monitors (e.g., 102-1-102-8) which are disposedat various locations of perimeter hallway 405 and a service area 406which is not normally accessible to the public. Real-time environmentalmonitors 102-9, 102-10, 102-11, and 102-12 are located within rooms 401,402, 402, and 404 respectively. Also shown in FIG. 4, are a plurality ofposition monitors (e.g., 103-1-103-8) which are disposed at variouslocation of perimeter hallway 405 and service area 406. Positionmonitors 103-9, 103-10, 103-11, and 103-12 are located within rooms 401,402, 402, and 404 respectively. Fixed displays 123-1, 123-2, and 123-3are disposed in perimeter hallway 405 while fixed display 123-4 isdisposed in service area 406. In FIG. 4, secured box 410 comprises asecure location at which a removable hard drive (not shown) is locatedand upon which database 160, or a copy thereof, is stored. It is notedthat in accordance with various embodiments, real-time environmentalmonitors 102 can monitor one or more conditions within building 400using smoke monitors, heat monitors, gas monitors (e.g., CO, CO₂,monitors, natural gas monitors, radon monitors, toxic fume monitors,etc.), light monitors, radiation monitors, earthquake monitors, cameras(e.g., video cameras, infra-red cameras, thermal imagers, lightintensifying cameras, etc.) or a combination thereof. In accordance withvarious embodiments, the location of each real-time environmentalmonitor 102 is recorded within real-time digital map 170. Furthermore,the location of each of position monitors 103 is similarly recordedwithin real-time digital map 170. In at least one embodiment, thefunctionality of a real-time environmental monitor 102 and a positionmonitor 103 can be implemented in the same device.

As an example, a fire 450 is detected by one or more of real-timeenvironmental monitors 102-3, 102-4, 102-5, and 102-6. This is reportedto environmental condition monitor 250 of control system 150 whichautomatically triggers an emergency notification to the fire department.It is noted that control system 150 may be located in a different partof building 400 (e.g., in room 401), or at a remote location operated bya third party or the emergency responders of the community in whichbuilding 400 is located. In the present example, as database 160 islocated in a removable hard drive (not shown) located in secured box410, the location of secured box 410 is conveyed to emergency responderagent 180. As described above, emergency responders may access securedbox 410 using, for example, a fireman's key, or a combination which isconveyed along with the location of secured box 410 to emergencyresponder agent 180 when the emergency notification is triggered.Alternatively, control system 150 may remotely unlock secured box 410,or convey to emergency responder agent 180 the location at which keysare stored which can be used to unlock secured box 410. Upon gainingaccess to database 160, emergency responders can view real-time digitalmap 170 of building 400. In so doing, real-time digital map 170 willdisplay the most recent internal configuration of building 400 onrecord. Real-time digital map 170 will also display information from oneor more of real-time environmental monitors 102-3, 102-4, 102-5, and102-6 which will help emergency responders to determine the type andlocation of the event which triggered an emergency notification. Usingposition monitors 103, emergency responders will also be able todetermine the location within building 400 at which in-room devices121-1, 121-2, 121-3, and 121-4 are located, as well as any cellphones120 (e.g., cellphone 120-1 located in room 401), wearable devices 124,and/or tablet/phablets 125, or similar devices, within building 400which have downloaded evacuation agent program 130. In one embodiment,even if a user does not register their private device for downloadingevacuation agent program 130 onto the device, position monitors 103 candetect that a device of some sort, even though not registered withcontrol system 150, is in building 400. For example, if the user'sprivate device interacts with a Bluetooth device, Wi-Fi router, or RFIDreader (e.g., position monitors 103) within building 400 this indicatesthat an anonymous user is in the building and provide some positioninformation which can be used by emergency responders in determiningwhether building 400 is still occupied and some information regardingthat person's location. Additionally, evacuation routes displayed onreal-time digital map 170 will be shown on fixed displays 123-1, 123-2,123-3, and 123-4 when an emergency notification is triggered. In oneembodiment, in-room devices 121 will generate a signal to control system150 when they are removed from a docking station, thus indicating that auser has picked up that device in response to an emergency notification.In accordance with various embodiments, this can be a signal to controlsystem 150 to trigger an emergency notification to emergency responderagent 180 as well as triggering localized emergency notifications withinbuilding 400 including, but not limited to, registered devices (e.g.,cellphones 120, in-room devices 121, fixed displays 123, wearabledevices 124, and/or tablet/phablets 125) and other alarms. In variousembodiments, this can include verification (e.g., in person, usingreal-time environmental monitors 102, and/or speaking with the user viain-room device 121). In accordance with various embodiments, a user'spersonal device (e.g., cellphones 120, wearable devices 124, andtablets/phablets 125) may display an icon for triggering evacuationagent program 130. As an example, when a user activates the icon forevacuation agent program 130, this will initiate triggering an emergencynotification as described above. In accordance with various embodiments,this triggering of an emergency notification by a user's personal deviceis performed via short-range communication networks (e.g., Wi-Firouters, Bluetooth components, or other short-range wirelesscommunication devices) and cannot be triggered using a cellularcommunication network. This is to prevent a user from accidentallyinitiating the triggering of an emergency notification for building 400when the user is no longer in the vicinity of building 400. For example,a guest at a hotel may forget to delete evacuation agent program 130after they have checked out of the hotel. In order to prevent the userfrom inadvertently triggering an emergency notification, this feature isperformed from a user's personal device using short-range communicationnetworks. In a similar manner, a person in building 400 can initiatetriggering an emergency notification via the evacuation agent program130 resident upon a fixed display 123 (e.g., wall-mounted evacuationdisplays or information kiosks) located within building 400.

This information can also be used by control system 150 to report thelocation of people within building 400, as part of the real-time updates190 of real-time digital map 170, sent to emergency responder agent 180.For example, if people in rooms 401 and 402 pickup in-room devices 121-1and 121-4 respectively in response to the triggering of an emergencynotification, this indicates to control system 150 that people are atthe location of those devices as reported by position monitors 103. Invarious embodiments, this can include verification (e.g., in person,using real-time environmental monitors 102, and/or speaking with theuser via in-room device 121). Additionally, as neither of in-roomdevices 121-2 and 121-3 were picked up, this indicates to control system150 that people may not be in those locations. Additionally, thelocation of a user of cellphone 120-1 in room 401 will be reported inreal-time digital map 170 to emergency responder agent 180.

FIG. 5 is a flowchart of a method of implementing a responder-readyreporting network in accordance with various embodiments. In operation510 of FIG. 5, a real-time digital map of a selected environment ismanaged using a control system implemented by a processor. As describedabove, the real-time digital map 170 comprises the most up to date 2-D,and possibly 3-D as well, representation of the physical configurationof a selected environment (e.g., building 400 of FIG. 4) including thelocation of walls, doors, stairwells, rooms, partitions, emergencyequipment, toxic/volatile materials, construction materials, etc.Furthermore, the real-time digital map 170 comprises real-time positionlocation information regarding handheld devices (e.g., cellphones 120,in-room devices 121, wearable devices 124, and/or tablet/phablets 125)which may indicate the location of a user of those devices. As describedabove, in various embodiments the selected environment comprises aconstructed environment having a network of environmental monitors 102and position monitors 103 embedded therein. In accordance with variousembodiments, as additional information is received and processed bycontrol system 150 (e.g., from environmental monitors 102 and/orposition monitors 103), control system 150 can generate updates (e.g.,190 of FIG. 1) to the real-time digital map accessed by emergencyresponder agent 180, or newly updated real-time digital maps 170 can begenerated based upon received reports (e.g., environmental data fromreal-time environmental monitors 102, position data from positionmonitors 103, and/or updates 190 received from cellphones 120, in-roomdevices 121, fixed displays 123, wearable devices 124, and/ortablets/phablets 125). These real-time updates/updated maps are sent tocellphones 120, in-room devices 121, and emergency responder agents 180.

In operation 520 of FIG. 5, the real-time digital map of the selectedenvironment is stored using a data storage repository coupled with thecontrol system. As described above, real-time digital map 170 is storedon database 160 which can be located at the selected environment, orremote from it. Furthermore, database 160 can be operated by athird-party provider, an owner/operator of the selected environment, orby an emergency services agency. In at least one embodiment, a securedbox (e.g., 410 of FIG. 4) at the premises of building 400 stores aremovable data storage device (e.g., a hard disk drive, USB drive, etc.)comprising database 160 and real-time digital map 170 and other data(e.g., a web-link to database 160, user identification and password)which may be useful to emergency responder services. In accordance withvarious embodiments, the real-time digital map 170 is a 2-D map of theselected environment. Additionally, in accordance with variousembodiments, real-time digital map 170 comprises a 3-D map of theselected environment as well as the 2-D map described above.

In operation 530 of FIG. 5, data regarding the selected environment,including the real-time digital map, is conveyed to an emergencyresponder agent in response to the triggering of an emergencynotification regarding the selected environment using an emergencyresponder reporting component (e.g., 210 of FIG. 2) implemented by theprocessor. In accordance with various embodiments, this includesconveying an authorization (e.g., a web link, user name, and password)to remotely access the data storage repository by an emergency responderagent. In another embodiment, control system 150 actually sends the dataincluding real-time digital map 170 to an emergency responder agent. Inanother embodiment, control system 150 provides physical access to thedata storage repository. This can include, but is not limited to,providing the location and instructions such as lock combinations or thelocation of keys used for opening a secured box 410. Alternatively,control system 150 can be configured to remotely unlock and electroniclocking mechanism of secured box 410 for emergency responders.Additionally, control system 150 comprises a wireless communicationinterface (e.g., 240 of FIG. 2) which is configured to provide real-timecommunication between emergency responder agents and handheld wirelessdevices (e.g., cellphones 120 and/or in-room devices 121).

In FIG. 6, handheld wireless device 600 further comprises a positiondetermining component 640. In accordance with various embodiments,comprises hardware and/or processing logic for determining the locationof handheld wireless device 600. In accordance with various embodiments,position determining component 640 comprises a Global NavigationSatellite System (GNSS) receiver and/or other component configured todetermine the location of handheld wireless device 600 from externalradio signals. It is noted that the functionality of positiondetermining component 640 may be implemented by processor(s) 606A, 606B,and 606C. Furthermore, it is noted that determination of the position ofhandheld wireless device 600 may be determined by detecting theproximity to known features such as position monitors 103 by handheldwireless device 600, or by monitoring the position of handheld wirelessdevice 600 by control system 150. That is, positioning component 640, insome embodiments, utilizes Wi-Fi, Bluetooth, RFID, and/or other wirelesssignals for from a position monitors 103 in a positioning systemembedded in a constructed environment to perform position determination.In some embodiments, the positioning component 640 includes its owntransceiver for communicating with position monitors 103, while in otherembodiments, positioning component 640 relies on wireless communicationcomponent 630 for such communication. In one embodiment, handheldwireless device 600 can capture images of the interior of building 400and compare these images with a database of images using photogrammetrictechniques to determine its position within building 400. In oneembodiment, control system 150 can monitor the location of handheldwireless device 600 and send that location information to handheldwireless device 600 for display on display device 618. In FIG. 6,handheld wireless device 600 further comprises a microphone 642 coupledwith bus 604 to facilitate communicating with emergency responders, orother entities, who are involved in responding to an emergency atbuilding 400.

In the example shown in FIG. 4, each of rooms 401, 402, 403, and 404 areequipped with an in-room device 121 (e.g., 121-1, 121-2, 121-3, and121-4 respectively). In accordance with various embodiments, in roomdevices 121 are positioned in a docking station (not shown) whichprovides power to the in-room device 121 as well as a data connectionwith control system 150. Alternatively, in-room device may simply beequipped with a battery and have a pre-loaded version of digitalbuilding plans for building 400, or a downloaded copy of real-timedigital map 170, stored thereon. In another embodiment, a copy ofreal-time digital map 170 is automatically downloaded onto in-roomdevice 121 when an emergency notification is triggered. In theembodiment shown in FIG. 4, a default evacuation route 420 has beenidentified for room 403. In this case, in-room device 121-3 will displaya copy of real-time digital map 170 showing building 400 in addition toevacuation route 420 which will direct a user of in-room device 121-3 toan evacuation position 425.

Similarly, a guest or visitor to building 400 can register their privatedevice such as a cellphone 120, a wearable device 124, and/ortablet/phablet 125, laptop computer, PDA, etc. They can then downloadevacuation agent program 130 onto their device (e.g., at theregistration desk, by receiving a web link for downloading evacuationagent program 130, at a kiosk in the lobby, etc.). In so doing, theirdevice will be registered with control system 150 and, if an emergencynotification is triggered, be alerted by control system, downloadreal-time digital map 170 (e.g., a 2-D map of building 400 as well as a3-D map of building 400 in accordance with various embodiments), andreceive real-time updates 190 of the conditions within building 400.This includes evacuation routes within building 400. In accordance withvarious embodiments, control system 150 can receive information fromposition monitors 103 as a user of cellphone 120 moves throughoutbuilding 400 and continuously determine whether to generate a newevacuation route for that device based upon its position in building400.

In the following discussion, the term “handheld wireless device 600”will refer to either of specifically built evacuation navigationdevices, or handheld wireless devices (e.g., cellphones 120, tabletcomputers, wearable devices 124, and/or tablet/phablets 125, laptopcomputers, PDAs, or other personal devices, which have been adapted tothe purpose of evacuation navigation devices by downloading evacuationagent program 130 onto that device. Referring again to FIG. 4, when anemergency notification regarding building 400 has been triggered,control system 150 will generate a notification to each handheldwireless device 600 registered on the premises of building 400. In otherwords, each cellphone 120 having a copy of evacuation agent program 130resident thereon will receive a message indicating that an emergencynotification has been triggered. In at least one embodiment, the user ofcellphone 120 will be notified using the ringtone, buzzer, or othersignals configured for that device until a user manually responds. Thishelps to ensure that the user has been notified of the emergency. In oneembodiment, when the user manually responds, this response is noted bycontrol system 150 and indicates the presence and identity of a userwithin building 400.

Similarly, each in-room device 121 resident within building 400 withreceive a message indicating that an emergency notification has beentriggered. In this instance, when a user removes in-room device 121 froma docking station or cradle, a notification can be sent to controlsystem 150 which reports the location and identification of thatparticular in-room device 121. In accordance with various embodiments,in-room device 121 can be activated remotely when control system 150triggers and emergency notification, or when it is picked up by a user.It is noted that handheld wireless devices 600 registered with aparticular location can be proximate, but not within, a selected area.

In one embodiment, when an emergency notification has been triggered,control system 150 will automatically download a copy of real-timedigital map 170 (e.g., a 2-D map and/or 3-D map) onto each registeredhandheld wireless device 600 having evacuation agent program loadedthereon. Alternatively, a copy of real-time digital map 170 can bedownloaded onto each registered handheld wireless device 600 as part ofthe process of downloading evacuation agent program onto that device. Inthis instance, the handheld wireless device 600 can perform autonomouslyto determine its location within building 400. In accordance with oneembodiment, the handheld wireless device 600 can also, using evacuationagent program resident thereon, determine its own evacuation route(e.g., 430 of FIG. 4) based upon its location such as in room 402 inFIG. 4. This evacuation route can be a default evacuation route which isselected based upon the location at which the handheld wireless device600 is located. In one embodiment, this determination is made when anemergency notification has been triggered. Alternatively, evacuationagent program 130 can run in the background, in which case the positionof handheld wireless device 600 within building 400 is continuouslymonitored and the determination of which default evacuation route to useis continuously updated as a user moves through the building. Thisevacuation route, as well as real-time digital map 170 or portionsthereof, can be displayed on display device 618. Additionally, as eventstranspire within building 400, such as a fire at location 470 ofperimeter hallway 405, control system 150 can generate updates 190 whichinform each handheld wireless device 600 of conditions within, orproximate to, building 400. Thus, a user of handheld wireless device hasa portable device which provides evacuation navigation information whichcan be updated in real-time as conditions develop to assist them insafely evacuating a building or other location. As a result, if adefault evacuation route (e.g., 430 of FIG. 4) is no longer usable, analternative evacuation route (e.g., 420 of FIG. 4) can be generated inreal-time to assist in safely evacuating building 400. It is noted thathandheld wireless device 600 is well suited for use within buildings orother constructed environments in which GNSS navigation signals,cellular tower triangulation, or other navigation aids may beineffective. In the example of FIG. 4, in response to the fire atlocation 470 and notification via update 190, handheld wireless device600 can autonomously determine that evacuation route 430 is no longerviable as an escape route. As a result, handheld wireless device 600will automatically generate a second evacuation route (e.g., 420 of FIG.4) which leads through a service area 406 that is not normallyaccessible to the public. It is noted that conditions at otherlocations, such as an evacuation position (e.g., 425 of FIG. 4) may alsobe monitored by control system 150. Thus, if the evacuation position 425is unsafe for some reason, that information can be reported to handheldwireless device 600 so that alternative evacuation route(s) can beplanned to other evacuation positions. It is noted that in variousembodiments, an evacuation route may lead to a plurality of evacuationpositions. For example, in some environments such as a mine, factory, orrefinery, it may be desirable to access emergency equipment such as abreathing apparatus, fire resistant clothing, or the like to permitsafely evacuating the premises. In this instance, handheld wirelessdevice 600 may generate a first evacuation route to an interimdestination at which this equipment is stored and subsequently generateat least one more evacuation route to an evacuation position.

In accordance with various embodiments, a user of handheld wirelessdevice 600 can communicate with emergency responders via control system150 to report their location, conditions within building 400, how manypeople are with them, or other information such as medical needs etc.Furthermore, using image capture device 632 and/or light 638, handheldwireless device 600 can aid a user in navigating an evacuation route inaddition to displaying real-time digital map 170 and evacuation routeson display 618. Thus, a user of handheld wireless device 600 has aportable map (e.g., real-time digital map 170) of building 400 for usein an emergency rather than having to quickly memorize a wall mountedmap typically found in most buildings. Additionally, real-time digitalmap 170 can be updated to display the current conditions in building400, not only for emergency responders but evacuees using handheldwireless device 600 as well. In accordance with various embodiments,fixed displays 123 (e.g., wall-mounted evacuation displays orinformation kiosks) are updated in a similar manner to provide users,who do not have a handheld device, an evacuation map which displays thecurrent conditions in building 400 as well.

It is noted that rather than having handheld wireless device 600 performautonomously, the position monitoring and reporting can be performed inreal-time by control system 150. For example, control system 150 canperform real-time monitoring of evacuation routes and the location ofeach handheld wireless device 600 within or proximate to building 400.Thus, as an evacuee progresses along an evacuation route such asevacuation route 420 of FIG. 4, their proximity to successive positionmonitors (e.g., 103-7, 103-6 and 103-5 successively) can be detected andreported to control system 150 which monitors the progress of eachhandheld wireless device 600. It is noted that control system 150 canfurther generate updates 190 to emergency responder agents 180 to keepthem appraised of conditions within building 400 and the location ofeach registered handheld wireless device 600 within or proximate tobuilding 400. As discussed above, control system 150 can further monitorand report the location of unregistered handheld devices as well.Control system 150 can also generate evacuation routes for each handheldwireless device 600 on the premises of, or proximate to, building 400.In accordance with at least one embodiment, control system 150 can bydefault generate evacuation routes down hallways and other areasequipped with sprinkler systems or other safety features to enhance thesafety of evacuees from building 400.

In accordance with various embodiments, when a user of a handheldwireless device 600 reaches an evacuation position (e.g., 425 of FIG.4), this is automatically reported to control system 150. For example,if a handheld wireless device 600 detects its proximity to an RFIDdevice of building 400 such as position monitor 103-5, it can be assumedthat the user has successfully evacuated to the doorway leading toevacuation position 425. This will be automatically reported by thehandheld wireless device to control system 150 so that emergencyresponders have an accurate accounting of who has evacuated building 400and who still remains within. Alternatively, position monitor 103-5 candetect the proximity of handheld wireless device 600 and report thisinformation to control system 150. In another embodiment, eachevacuation position such as 425 of FIG. 4, is equipped with its ownreporting device such as position monitor 103-13 to report each handheldwireless device 600 in its proximity.

FIG. 7A is an example screenshot of a display of an evacuationnavigation device in accordance with various embodiments. In FIG. 7A,handheld wireless device 600 is shown displaying a copy of real-timedigital map 170 upon display device 618. In FIG. 7A, handheld wirelessdevice 600 is displaying evacuation route 420 from FIG. 4 to a user ofhandheld wireless device 600. Also shown in FIG. 7A is an icon 710 whichindicates the current position of handheld wireless device 600. It isnoted that in accordance with various embodiments, handheld wirelessdevice 600 may be configured with components which permit detecting theorientation (e.g., in one axis such as a horizontal azimuth, or a 3-axisorientation in the X, Y, and Z axes) of handheld wireless device 600.Thus, as a user moves and rotates handheld wireless device 600, theorientation of icon 710 will similarly rotate to convey the orientationof the user with respect to real-time digital map 170. In at least oneembodiment, a compass indicator is also displayed which rotates as theuser rotates handheld wireless device 600 to provide a better sense oforientation to the user. In accordance with various embodiments, thedisplay of real-time digital map 170 itself will auto-rotate as a usermoves so that the direction in which the user is facing is alwayspointed at the top of display device 618. In another embodiment, thedisplay of real-time digital map 170 is static and icon 710 moves androtates to indicate the direction a user is facing. In accordance withvarious embodiments, other visual clues can be provided as guidance fora user of handheld wireless device 600. For example, if a user isfollowing the evacuation route displayed on display device 618, the icon710, and/or the path displayed as evacuation route 420 may be displayedas green. If the user deviates from the displayed evacuation router bytaking a wrong turn, or if a change is dynamically made to the path ofthe evacuation route, the icon 710 and/or the path displayed asevacuation route 420 may be displayed as red. If a user is approachingsome feature, such as a turn in a hallway, doors, stairs, emergencyequipment, etc., the icon 710 and/or path displayed as evacuation route420 may be displayed as yellow. In accordance with at least oneembodiment, when icon 710 and/or evacuation route 420 are displayed inred or yellow for the conditions described above, they will also flashintermittently to gain the user's attention. Additionally, an audiblenotification such as a tone, or vocal warning, may be sounded to furtheralert the user. In FIG. 7A, a text box 720 also displays instructions tokeep a user appraised of alerts, conditions, instructions, and otherinformation useful in safely evacuating building 400. It is furthernoted that a vocal instruction which repeats the message shown in textbox 720 may also be sounded in various embodiments. Also shown in FIG.7A is a microphone 642 and speaker 701 for communicating with emergencyresponders. In accordance with at least one embodiment, display 618 isalso configured for displaying the real-time environment around handheldwireless device 600 as well as evacuation route information as shown inFIG. 7B. For example, when configured with image capture device 632, auser can capture real-time images of, for example, in FIG. 7B a hallway750 is displayed on display device 618. Overlaid on top of this imagewill be a representation of evacuation route 740 and icon 730 indicatingthe present location of the user of handheld wireless device 600 andorientation with respect to hallway 750. As shown in FIG. 7B, evacuationroute 740A shows the continuation of evacuation route 740 past a doorwhich otherwise blocks the viewing of the entirety of evacuation route7400 and indicates the user of handheld wireless device 600 that a turnis to be followed once the user has moved past the door.
